Hamedan, 
Iran
498,337 people lived in Hamedan in 2025. It is the 1109th largest of the world's 12,138 cities, and the 17th largest in Iran.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

How Hamedan grew
Count 10 people in Hamedan in 1975 and the same count gives 40.2 in 2025.
On the UN's projection it will have 506,844 people in 2050. It passed 250,000 people between 1990 and 1995.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

Where it is
How to read this: every dot is one of the 210 cities in Iran in 2025, and a dot's area is how many people live there, the biggest being Tehran. The ringed dot in colour is Hamedan; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Hamedan covered 76 km², and buildings, roads and other built-up land covered 18 km² of it. That is 36 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 2.9 times its size, and its people are 4 times as many.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in Iran
Its share of Iran
Of every 1,000 people in Iran in 2025, 5 lived in Hamedan, which is 498,337 people.
How to read this: shrink Iran to 1,000 people and this is what you get. The coloured squares are the ones who would live in Hamedan; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: the figure in front of a name is where that city stands among the 12,138 cities the UN counted in 2025, and each bar is its people, on one scale per list. Numbers are missing where a city has fewer than 300,000 people and so has no page of its own.
Apparatus
Sources and method
The figures for Hamedan are the UN's own, at five-year steps: an estimate for each of 1975 to 2025, then projection to 2050. Projected years are drawn hatched, and the UN publishes no range of uncertainty for a city. What a city means here, how the UN measures one, and why that number can differ from the one Hamedan publishes about itself: how the figures here are put together.
